iOS Twitter和Facebook iOS自动布局 iOS内存管理 Twitter已集成在 iOS 5.0中 ,Facebook已集成在 iOS 6.0 中。我们的教程侧重于使用Apple提供的类,Twitter和Facebook的部署目标分别是iOS 5.0和iOS 6.0。 涉及的步骤 第1步 - 创建一个简单的基于视图的应用程序。 步骤2 - 选择项目文件,然后选择 目标 ,然后在 选择框架中 添加 Social.framewor k和 Accounts.framework 。 ** 步骤3 - 添加两个名为facebookPost和twitterPost的按钮,并为它们创建ibActions。 第4步 - 更新 ViewController.h 如下 #import <Social/Social.h> #import <Accounts/Accounts.h> #import <UIKit/UIKit.h> @interface ViewController : UIViewController -(IBAction)twitterPost:(id)sender; -(IBAction)facebookPost:(id)sender; @end 第5步 - 更新 ViewController.m 如下 #import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } -(IBAction)facebookPost:(id)sender { SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){ if (result == SLComposeViewControllerResultCancelled) { NSLog(@"Cancelled"); } else { NSLog(@"Done"); } [controller dismissViewControllerAnimated:YES completion:nil]; }; controller.completionHandler = myBlock; //Adding the Text to the facebook post value from iOS [controller setInitialText:@"My test post"]; //Adding the URL to the facebook post value from iOS [controller addURL:[NSURL URLWithString:@"http://www.test.com"]]; //Adding the Text to the facebook post value from iOS [self presentViewController:controller animated:YES completion:nil]; } -(IBAction)twitterPost:(id)sender { SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; [tweetSheet setInitialText:@"My test tweet"]; [self presentModalViewController:tweetSheet animated:YES]; } @end 输出 当我们运行应用程序并单击facebookPost时,我们将获得以下输出 - 当我们点击twitterPost时,我们将获得以下输出 - iOS自动布局 iOS内存管理
